To all whom it may concern.

Be it known that I, Gnoncn H. Boyn'row, a citizen of the United States of America, residing at Pittstield, in the county of Berlishire and State of lilassachusctts, have in vented new and useful Improvements in lVeighing Attachments for \Vool-leeding Machines, of which the following is a specification.

This invention relates to improvements 1n chines.

An objectof the invention is to provide a delicate attachment for wool-working machines whereby the weight of the yarn that falls into the weighing receptacle may be very accurately determined.

I-Ieretofore, it. often occurs that the run or weight. of the yarn is not known until it has been woven into the finished cloth. when it. is too late to correct the error. ()t'tein times, C'llSl()l'Yl(l'. r ish a wool cloth or weave of a definite weight per yard. and. as stated, it the weight ol the finished ('lolh does not agree with the wei ht called to a loss in the My inven tion is therelore designed to overcome this objection and to provide the weighing machine attendant with an accurate derive tor indicating the weight or run ol. the yarn in the scale pan before the machine is tripped to discharge the yarn.

Broadly, the invention consists in providing the scale or weighing beam with a poise that can he rery accurately adjusted to any run of yarn, and, in addition, a pointer device by means of which the machine attendant can readily determine the position of the poise by means of the pointer.

Referring to the drawings which form a part. oi the specif .ation and in which--- Figure 1 a side elevation of the ii'uprovcmerit, show'ligthe poise attachedto and in place on the scale beam; Fig. 2 is a trans verse sectional view on the broken line of Fig. 1 and showing the scale beam in section, 111K. the poise in outline; Fig. 3 is a. transverse sectional YlOW on the line 3 of Fig. l howing the interior construction of the poise and the mechanism for operat. ing he po nter: and Fig, 4 is a. side elevation of the tree end of the scale beam showing the interior construction of the poise box and the adjusting screw or worm.

Referring to the drawings in dctail,---a designates the usual scale beam of a woolfeeding machine that is pivoted to the framework of the machine at b by means of the bracket-arm 0. Attached to the scale-beam (1. is the receptacle (Z into which the yarn falls. The contents of this pan are automatically discharged by means of the usual trip-mechanism that is attached to thebcam o by means of the rod 0 which causes the usual doors of the receptacle (1 to open when the weight of the yarn in the receptacle ovenbalances the poise carried by the scalehcam. This part of the description. of a wool teeding machine is of common construction and need not be referred to in detail. v

Coming now to the construction and 0peration of my specific improvement,f.

designates a hollow Ushapcd poise-member that is mounted on the scale-beam a, an opening being formed in. the sides of the poise at. suhstzmtially opposite points, as indicated in Fig. 4 at, g and it. I ixedly secured lo the beam a is a bracket-arm 2' by llltzlllH ol stud j and set-screw 7c. The lower end of the arm 2' is split as indicated at m. A transversely-arranged screw 0 passes through the lower end portion of thebracket. 'i, as shown, and is for the purpose of drawing the two separated portions of the bracket together to produce a chunping o1- pinching Gil'fQCt on the threaded rod 7; which passes through a threaded opening in the bracket 7'. This threaded rod is for the purpose of adjusting' the position of the poise f and to oft'ect this result the rod 7) is passed through the opening 1' at one side, of the qoiso f and an opening 3 at the other side oi the poise, and at this latter opening a stud or pin it enters a groove in the rod 79 in order to retain the threaded rod in place. A spring 11. is located between the poise f and the milled head 1: of the rod 7; in orderto take up any lost motion between the threaded rod and the poise. It will, therefore, be seen that whe1. the rod 7) is rotated the oise is moved along-the. scale-beam a. For t 1e purpose of in -i aling this adjustment of the poise and to determine the run or weight oi the yarn ir the receptacle d, a pointer in is operated at the same time that the milled head 1 is rotated. To ei'lect the movement of the pointer t, a worm-gear .n is arranged to engage the worm y of the thread that lies within the poise This worm gear is mounted in the boss 3 of the graduated cover 4 which secured to the poise f by means of screws 5. The rotation of the milled head n will, of course, cause the pointer in to move in unison as the poise f is moved along the beam (1 and preferably in the direction in which the worm g is ro-- tated;-that is to say, when the pointer moves in the direction of the hands of a clock the screw is turned right-handedly.

Referring now to the use and operation of the improvement and first considering the cover 4 as being arbitrarily divided into 3(30 divisions or degrees: If a two run yarn, which weighs, say, 225 grains, of 1000 yards, is required, the pointer 10 is arbitrarily set at 45 from the zero position, indicated at the top of the dial-plate. if a three run yarn is required, the pointer is turned backward from the zero position, as, for instance, to 315, it being understood that the t three run yarn is lighter in weight than the two run, as, for example, 175 grains, while the two run may weigh 225 grains, and a four run may weigh 125 grains, in which case the pointer would be turned still farther back. The pointer .can, therefore, be set for any particular f run of yarn and, simultaneously, adjust or position the poise or that run. After the dial has been set for a particular i run, the screw 0 is tightened to retain the poise in place.

it is, of course, understood that the graduations of the dial plate or cover L are merely arbitrary. They merely indicate, in

a general way, to the workman that by trial and experiment 1000 yards of yarn will weigh 225 grains when the pointer indicates 45. It is, of course, understood that the rotation of the pointer so simultaneously moves the poise on the scale beam or arm a.

\Vhat I claim, is,-

In a yarn-weighing mechanism for woolfeeding machines, the combination, with the sczle-beam of the machine, av receptacle to receive the yarn to be weighed attached to the scale-beam, a hollow poise slidably mounted on said beam, a bracket fixedly secured to the beam and having a threaded opening therein, a threaded rod passing through said opening in the bracket, meansv to rotatably attach the rod to the poise, a wormgear rotatably mounted within the poise and engaging the worm en the rod that lies within the poise, a spring to take up any lost motion of the rod, apointer secured to and moving with the worm gear, whereby when the rod is rotated the pointer will move in unison with the poise, and a graduated dial over which the pointer moves to designate the position of the poise and to determine the weight or run of material being weighed, and means on the bracket to re ti l) tain the poise and threaded rod in place,

as described. i
